Patents by Inventor Yongwon Jung

Yongwon Jung has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cysteine-tagged streptococcal protein G variant
    Patent number: 8541005
    Abstract: The present invention relates to an N-terminal cysteine-tagged Streptococcal protein G variant. Since the variant binds in a directional manner to a surface of a biochip or a biosensor, the variant provides a biochip and a biosensor having an improved antibody-immobilizing capability, compared with an untagged protein G variant.
    Type: Grant
    Filed: June 20, 2007
    Date of Patent: September 24, 2013
    Assignee: Korea Research Institute of Bioscience and Biotechnology
    Inventors: Bong Hyun Chung, Jeong Min Lee, Sun-Ok Jung, Yongwon Jung
  • Method for preparing antibody monolayers which have controlled orientation using peptide hybrid
    Patent number: 8236509
    Abstract: The present invention relates to a method for preparing an protein monolayer using a peptide hybrid for protein immobilization, more precisely a peptide hybrid for protein immobilization which has improved solubility by introducing a PEG linker and a proper reaction group to the oligopeptide having specific affinity to selected types of proteins and is designed to provide enough space between solid substrates and proteins immobilized, whereby various solid substrates treated by the hybrid catch specific proteins effectively on. The peptide hybrid for protein immobilization of the present invention facilitates the control of orientation of an antibody on various solid surfaces and immobilization of various antibodies of different origins or having different isotypes with different affinity. Therefore, the surface treatment technique using the peptide hybrid of the invention can be effectively used for the production of various immunosensors and immune chips.
